       Collocation
       Collocation is used in the sense J.R. Firth used it: ‘the company
words keep’. Put differently, words generally co-occur in groups that
conform to grammatical and semantic usage, e.g. strong/weak/black/
Ceylon, etc. tea (Adj + N). While the majority of collocations in a
language are ad hoc, some are habitual in that they recur. These
latter, along with idioms, exemplify the idiom princi ple
       Discourse
       In this book, discourse is used to signify an organized piece of
language, spoken or written, functioning at a level above the units of
grammar, though composed of these units at the micro-level. An ex-
tract from a complete discourse, the macro-level, can also be referred to
as a discourse as it comes from the same continuous piece of language.
       Iidiom
       This term exemplifies the form of the headword of this item in
dictionaries. It is used in this book in two senses:
       1) A conventionalized multiword expression, often, but not always,
literal. Idiom in this sense is very close to the OED definition;
       2) Idiom is also used to refer to the structural design of a language,
for example, the extent to which deletions are acceptable in locutions,
spoken or written, as well as conventionalized, but non-canonical, idio-
syncrasies peculiar to a given language. This second sense of idiom is the
same as that given by the OED definition. There are, of course, idioms
such as nothing loath or for better or worse to which both of the OED
definitions apply, as they are expressions which, though idiosyncratic,
are conventionalized.
       Idiomatic
       This term signifies conformity with the usage of a language.
       Register
       Register is used in the Hallidayan sense: a specific register is
created when a choice of forms, lexical, grammatical, and discoursal,
dictated by field, or subject matter, tenor, or partici pant relations
and mode, or channel of communication, is made. Legalese is a
strong example of a register, journalese a less strong one, not being
governed as legalese is by the rigorous language conventions of an
institution such as the law.
       Rrestricted collocation
       This term refers to a group of words which co-occur with each
other only in limited ways, e.g. shrug one’s shoulders, addled eggs/brains.
